What is a gastric bypass?
Is an operation where the stomach is reduced and the digestive tract is diverted. Literally, the term means circumventing the stomach. With this procedure, serious forms of overweight can be treated, especially the so-called morbid obesity. The stomach is reduced, sometimes to only 10% of its original size, and further connected to the small intestine. A gastric bypass ensures that both less food can be taken (a so-called restrictive procedure), and can be included (this is also called malabsorption).
Because of the smaller stomach and because the food flow is diverted outside the 12-finger intestine and the first part of the small intestine (gastric bypass or gastric bypass), this results in weight loss.
Praktijk Gabriels acts as a mediator. Registration and follow-up appointments are offered in Barendrecht (NL). Our patients are treated under the responsibility of and in a bariatric center in Belgium.
How does a gastric bypass surgery work?
First, the doctor makes a smaller stomach bag from the upper part of the stomach. The new stomach has about the volume of an espresso cup and thus ensures that you can eat less. Then this new stomach bag is connected to the small intestine. The passage to the rest of the stomach is closed, but the rest of the stomach remains in the body. With a gastric sleeve, the rest of the stomach is removed, so not with the gastric bypass. Finally, the end of the duodenum is connected to the small intestine. This ensures that the stomach, bile and pancreatic juices still end up in the food, so that it can be digested.

We understand very well that it is a big step to make a first appointment for a bariatric procedure. That is why you can expect us to fully support you in this, if you want to. We advise you to bring your partner or good knowledge to the first consultation.
During the first consultation, we discuss all topics related to the treatments. This is how we approach the conversation about what is most disturbing to your body and what you would like to change about it. The methods and operation techniques will also be discussed and researched which suits you best, what results you can expect, what the possible risks of this intervention are and how the aftercare will look like. You will always receive honest advice and will be informed in a clear way about the treatment and the period that follows.
During the first consultation, the consultant also checks whether you are a suitable candidate for the bariatric procedure of your choice. The surgeon will ask about your health, medical background and any medication. If you use blood-thinning medication, you must stop at least one week before treatment.
After this initial consultation, you can make the right choice. We understand that during the first consultation a lot of information comes to you. Do not hesitate to contact us after this conversation.
What are the advantages and disadvantages of a gastric bypass?
There are advantages and disadvantages to every operation. The biggest advantage of the gastric bypass is that you quickly lose a lot of weight and can therefore quickly reach a healthy weight. It is important to mention that the gastric bypass is a tool. It is possible to gain weight again after a gastric bypass. When you fit your lifestyle, and therefore eat less and move more, you will maintain the healthy weight. A disadvantage of the gastric bypass is that the digestive juices later end up at the food, so that the body can digest food less well.

You are not hungry
A gastric bypass is performed via a viewing operation
The scars are small, allowing you to recover quickly.
The following complications can occur during or after the procedure:
Seam leakage. The doctor has to make new connections for the stomach to work optimally. These connections can sometimes leak.
Vitamin deficiency. What you can do best in this case is stay calm, lie down quietly and drink water. When you have had a gastric bypass performed, you will have to swallow vitamins, because the small portions that you can now eat do not provide enough vitamins.
Dumping. Dumping occurs when high-calorie food enters the small intestine too quickly. Think of sugars, fats and carbohydrates. Because the blood goes to the gut, the blood pressure drops in the brain, making you sleepy or dizzy. It can also cause palpitations and you can sweat excessively.
What can I expect after a gastric bypass?
A gastric bypass has a big impact on your life. You have to eat differently and more consciously because your body can process and absorb less food. For example, you have to take extra vitamins every day after the stomach reduction. After the surgery, you must eat liquid or ground food for three weeks, so that the stitches in the stomach can heal well.
It is also important that you adjust your lifestyle. Only because of this will you permanently lose weight. Because of this weight loss you have fewer health problems. These can even disappear. Your quality of life will also greatly improve.
After the procedure, you can walk straight away and return home after an average of two days. A day after returning home you will be called by us to make an appointment for the first check. Furthermore, the dietary agreements must be clear, if that is not the case then we will gladly help you further. We are available by phone every day.
Two weeks after the procedure you have a check-up with the bariatric nurse.
After three months, six months, nine months and a year, you have re-checked the bariatric nurse in the practice of Diana Gabriels. It will always be examined which adaptation is needed.
If necessary, extra agreements are made with specific problems. After six months, we advise to prick blood at the GP. This to control the vitamins. This is then repeated at least once a year to check the nutritional and vitamin levels in the blood. If necessary, shortages will be started with additional medication.
From the first year after surgery, an inspection will take place twice a year for five years.
During the first two weeks, you should be more relaxed for a good wound healing. After these two weeks, if the wounds have recovered properly, you can do everything again.
It is then already important to get enough physical activity. This has a positive influence on the end result. By burning more calories, you lose more weight and stimulate the muscles. See which activities suit you and do what you like. Moving together often works motivating.
In any case, ensure that you get physical exercise for at least half an hour every day, such as swimming, walking, jogging and fitness. Even small changes make a lot of difference. Take for example the stairs instead of the elevator and walk (if possible) to appointments and shops. You can also park the car just a little further away.
Sports and exercise will ultimately have to become a logical and permanent part of your new way of life. That is healthier and it helps to keep your new weight stable. You get this better and easier for each other under supervision, by a movement therapist or in a group.
Regardless of the treatment (*), it is possible to lose up to 100% of your excess weight after the Band, Sleeve and Bypass, if BMI <40. The target weight is then BMI 23-25
If BMI ≥40 is statistically lost 70% of the excess weight.
